Ever wonder how Mike Vick woulda lived if he never got tossed behind bars for dog fighting??
Thanks to Jamal Anderson ... no need for imagination anymore -- 'cause the ex-Falcons star is selling the mansion that was built for the QB!!
The crib's out in Loganville, GA ... and Vick was having it done so he could live out his Falcon-playing days near the ATL. But, he never got to move into it 'cause of his prison sentence.
The QB's loss turned out to be Anderson's gain .
